I do believe in prosecutorial immunity, to a point. And I do believe that the state has a vested interest in investigating such cases.
However, once found that a truly innocent man is in their snare the gov't should be REQUIRED to make up to the person destroyed the monetary loss of his livelihood. Not punitive, but true monetary loss, determined by a 3rd party arbitor not on the state's payroll.
I did not lose as much as this man, but I have some idea of his loss.
God be with him, and God bless his wife.
